It all started out as more of a joke and a way to get some attention and a few laughs. Now it has Chris Fondell of Alaska Jewelry Inc thinking he needs to engineer a way to make this idea, The Remember Ring a reality.
So what is this idea? The ring, made for men will warm up every year before an anniversary, “reminding him that yes, he started wearing jewelry for a very important reason.” The temperature would start at 120 degrees farenheight and would continue getting warmer throughout the day right before the anniersary. The heat would last for about 10 seconds to give you that short but constant reminder that you better not forget!
The idea is that there would be no need for batteries because the micro thermopile would convert heat from your hand into electricity to keep it charged and ready to go. I could see some people with a ring on every finger for birthdays, anniversaries, etc. 
This whole concept could actually really be a great idea. With circuits continually getting smaller and smaller, what else could they fit into a ring?

Odd people with translucent skin have managed to run Linux on a wrist-watch – but I think the electronic jewellery market will be short lived at best. One vital part of the whole idea of remembering an anniversary is because it’s supposed to be important to you – heat up rings would tilt the playing field.
I want a Remember Ring connected wireless with Google Calendar
.
There’s not even a decent desktop program that can connect to Google Calendar so it might be a little while to get a ring that would do it.
Think about how cool a watch would be that could sync with Google Calendar! That would be sweet!
